Replace CurFunctionDecl and CurMethodDecl with methods getCurFunctionDecl() and getCurMethodDecl() that return the appropriate Decl through CurContext.

used to mutate the attribute list for declspecs when the type was 
converted, breaking the case where one declspec was shared by multiple
declarators.

This fixes rdar://6032532.

The assert at Sema::ObjCActOnStartOfMethodDef should check CurMethodDecl instead of CurFunctionDecl.

Note that Parser::ParseCXXMemberSpecification is temporarily disabled until the Sema support is in place.
Once ParseCXXMemberSpecification is enabled, the Parser/cxx-class.cpp test will pass.

ObjCMessageExpr objects that represent messages to class methods now can contain the ObjCInterfaceDecl* of the target class if it was available when the ObjCMessageExpr object was constructed.  The original interfaces of the class has been preserved (requiring no functionality changes from clients), but now a "getClasSInfo" method returns both the ObjCInterfaceDecl* and IdentifierInfo* of the target class.

"this patch adds code generation hooks for Objective-C constant strings.  It also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found.  This is consistent with Apple GCC.  I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it.  Possibly there is a way of making the error go away, but I haven't found out what it is yet."

"This moves built-in Objective-C types up the scope chains to where they can be replaced by versions included from the runtime library's headers."

This makes it ok to use @"foo" without a declaration for NSConstantString.

isn't guaranteed to exist. This fixes a crash with conflicting typedefs
coming from stdin.

This also fixes the crash in PR2406, but doesn't completely fix the 
issue; it appears there's something strange about the physical location 
for the definition of int64_t in stdlib.h.

-ScopedDecls get chained to their DeclContext.
-DeclContext's DeclChain replaces FunctionDecl's DeclChain and EnumDecl's ElementList.

  Added TagKind enum.
  Added getTagKind() method.
  Added convenience methods: isEnum(), isStruct(), isUnion(), isClass().
-RecordDecl/CXXRecordDecl::Create() accept a TagKind enum instead of a DeclKind one.

pointer cast hack currently in isIntegerConstantExpr 
(in lib/AST/Expr.cpp).  Also removes an odd test that even gcc doesn't accept.

The reason the pointer cast hack is relevant here is that it makes Sema 
end up misinterpreting the relevant expression as a null pointer constant.

The reason for this patch is that I plan to remove the pointer cast hack 
sometime soon because it causes strange issues, especially in its 
current form; see my recent email to cfe-dev
"[PATCH] add constant expression evaluation to the AST and fix PR2413".

- Changed Sema::ObjCActOnStartOfMethodDef() to more accurately type "self" in factory methods.
- Changed Sema::ActOnInstanceMessage() to use the new type to restrict the lookup.
